A few of your stories jogged memories. My pit had vicious separation anxiety. It's at the root of most of his fables.
My buddy had a gig doing property management in Napa on a 25-acre estate. He stopped Sammy at the door and said no dogs allowed inside, walk him around. The nearest road was 1/2 mile away and his Rottie buddy was out back, so I shut the door on him. No fences, I thought he would walk around.
After 20 minutes of AWOL, I hesitantly go back to the front door to find him gradually chewing through it. They were $10K, 12' tall oak doors, custom. Learned a lot about wood filler and color matching over the next 24 hours. Fucking dog.
One year foxtails got bad, and he snorfed one after the other, each cost $200 to extricate under anesthesia. I started flipping my shit when I heard the sneezing because I couldn't afford it. He finally suppressed, by sheer force of will, any outward sign of a foxtail. But I knew.
Drag him to the vet for removal #5 that summer and the newb DVM girl says "no fucking way, he would be freaking out if he had one, no refunds if I don't find it, you're kinda sounding dumb here..." Calling upon every bit of restraint I had, I said just go ahead and check, I get it. Well, what do you know! She hands me the bloody remains on a gauze pad, like she discovered a new species. "I'll be back, next time just do it without the lecture please."
Like Mad I was taken out by rough play hundreds of times at the dog park and in backyards, just without serious injury. I left him with my parents maybe 5X over his 13-year life. Two of those times he brazenly walked away to mate with his friend down the street, creating sheer havoc and a bloody mess both times. He tried to stop my truck while we were navigating treacherous back roads in the Sawtooths by standing in front of it and got run over. Checked his poop for a couple days. No blood, the hike went on. Found out city dogs don't withstand granite walking surfaces well. Tracked blood for 3 days until things scabbed over. Found out pits need jackets below 50F.
I learned patience with that dog and learned I never want a dog again. I don't know how you all do it. They are like destructive toddlers that never grow up. We dog-sit the minis owned by our neighbors and I love dogs, just not enough to own one.
